macclurei provenance family forest.【Result】Timber characteristics among families existed significant differences ( P<0.01) and had great selection potentials.
【Objective】To understand genetic variation characteristics and provide bases for superior families selection and germplasm resources reasonable exploitation and utilization in Michelia macclurei based on estimation of wood property genetic parameters among families and correlation analyses between wood properties and growth traits.【Method】Genetic variation characteristics of wood basic density, fiber length, fiber width and fiber length/width ratio were analyzed using 100 families in M.
